Latest Patents

One of her latest patents is titled "Differential z-axis resonant accelerometry." This invention features a MEMS resonant accelerometer that includes two proof masses designed to resonate when driven by periodic signals. Each proof mass is equipped with a resonator structure that vibrates relative to the proof mass and a dummy structure that remains static. By analyzing the frequency at which the resonators vibrate, the device can determine the magnitude of acceleration in a direction perpendicular to the planes of the proof masses. A differential oscillation frequency can be computed from the two sensed frequencies, enhancing measurement precision.

Another notable patent is "Multiple-axis resonant accelerometers." This invention is based on detecting changes in resonance frequency of one or more electrostatically-driven resonator masses due to electrostatic gap changes under acceleration. The resonator masses are configured to resonate simultaneously in different directions, corresponding to various axes of sensitivity, such as X, Y, and Z axes. The motion of each resonator mass is monitored through electrostatically-coupled sense electrodes, allowing for accurate acceleration measurement along specific axes.
